Active Speaker won't power up

i would check the power supply and the power amp! There must be a short in there.Honestly,it needs a well complete check by a pro! Thank's! Serge Lavallee!

You just fix the power supply and Brige and check the transformer

The bad news is it could be any of them. or it could be the lighting- CFL's and regular flourescent lighting are bad for audio, as are switching supplies used in TV's, microwave ovens and some musical gear. They are worse than lighting dimmers for noise.

The thing to do is start at the speaker itself and work through the chain of devices to find the one distorting. An old transistor radio is useful here. Most actually do have enough power to faintly drive a large speaker- listen for scraping and rattling- it would mean the voice coil windings may have come loose or the coil form is damaged from heat.

Move back to the amp input and try again- this time listen for a clipped sound if the speaker checked out okay. It would sound like the Charlie Brown adults in the cartoons. That would be a failure of an active component in the amp. If you now hear rattling or scraping- the speaker voice coil is bad and should be repaired or replaced.

If it sounds good, move back to each deck. apply your radio- volume turned down to an input it one is provided. Each should sound clean like the amp did. If no sound or distorted sound is found here- which is the most probable location, it is likely one of the IC chips is at fault. Likely a 4558 if an IC fault, otherwise suspect dirt or hair on the encoder connected to the spin platters.

Short answer from personal experience.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.

Connect the Active EQ between the pre-outs and the amp input.

Run speaker assignment, levels, etc and have fun.

Helpful Hint: If you don't have sufficient between-speaker room for proper reflection off the front wall you CAN turn the 901's around and you won't believe the amount of air these things push! I have actually felt it ten feet away after explosions or crashing ocean wave sounds. Now THAT is multi-media.

You mean BOSE 901 Series III Active Equalizer; and HARMAN KARDON AVR1600 right?

Sure it will. It goes in a Tape Loop such as Tape Out/In or Video 1 Out/In. But it won't work for anything except analog stereo sound sources as all digital audio is not available to the RECORD OUT jacks when the Tape or Video 1 is activated. AND 901 Active EQ is intended solely for 901's, not any other speaker system

The HK has no Line Level volume-controlled Pre-Outs so you're out of luck if you want the 901's to take part in a multichannel setup, which would require a separate power amp to drive them anyway.

These are a nice unit... just bought three of them that were dead... I have repaired one so far. I assume you mean the blue LED is on indicating power is on. What I want you to test is if injecting signal on the BACK of the unit jack (power amp in) will create sound. If it won't then better exercise your warranty. The one unit I have completed repair had a bad 15 volt regulator in it... the second that is almost fixed somebody had blasted the input circuits... probably connected to a speaker output... don't do it... these are LINE and MIC level units. If you need to tap off a speaker output, use a DI box with the unit. The third unit I have not received yet. Drummer used the repaired one as monitor last night and was impressed with the power this unit has.

By properly, you must mean WITH the Active EQ.

According to this picture, you're in luck BUT...

Page 17 provides guidance for connecting speakers to an HP A6332.

This excerpt on page 17 can be clarified by adding "IF," before the sentence.

"NOTE: Speakers may be passive (no power button and no power cord) or active (power
button or power cord). Your computer supports only active (powered) speaker systems; the
speaker system must have its own power cord."

This is an excerpt from page 21

"Speaker types

Speakers may be included with the monitor (select models only) or are sold separately.
Refer to the product documentation for your speakers.
Your computer supports only an active (powered) speaker system. An active speaker
system must have its own power cord. A home audio system does not require active
speakers, because the receiver provides amplification."

Generally speaking, manufacturers offer many types of speakers for use with their computers. If the speakers that originally came with your computer had a extrernal power supply, then it would probably be best to use externally powered speakers.

I have seen many older computers and even some budget computers that use the sound card for amplification. Most modern sound cards are primarilly focused on sound processing, and not necessarilly amplification.

Its impossible to know whether your system requires powered or non-powered speakers because I have no way of knowing your computers specific configuration. However, I think it is safe to say, if you use externally powered speakers in either case, you should be ok.

If you call the manufacturer, or go to its web site, your original computer configuration can normally be provided if you provide its serial number.

Hope this helps - Good Luck!

have your built-in amp checked for trouble. there should be trouble in the output stage feedback loop. this is something to be done by a repair technician
